摘要
简单介绍了二维(2D)层状过渡金属硫族化合物(transition metal dichalcogenide,TMD)材料中的激子,具体介绍了 TMD 材料的优缺点以及目前研究所面临的现状和问题,其中合成高产率、高性能的单层 TMD是 TMD作为下一代电子材料进一步发展的关键挑战.详细综述了基于 TMD中的激子对调控光致发光方法的最新进展,包括化学掺杂、衬底工程、抑制激子-激子湮灭(EEA)等方法,最后总结和展望了TMD材料目前研究现状存在的主要问题以及未来的需求与挑战.
Abstract
First,briefly introduce the excitons in 2D TMD material,and then the advantages and disadvantages of TMD materials and the current problems the research faces are introduced.The synthesis of high-yield,high-performance monolayer TMD is the most critical challenge for the further development of TMD as a next-generation electronic material,so the latest progress of exciton-based photoluminescence control methods based on exciton pairs in TMD is reviewed in detail,including chemical doping,substrate engineering,exciton-exciton annihilation inhibition(EEA)and other methods.Finally,the current research status of TMD materials,the main problems,and the future needs and challenges are prospected.
